I would like to get this idea out there before I forget it. I realize that when I am browsing the web, I spend a lot of my time simply reading the current web page. I wonder if it is feasible to reprogram Firefox or some other web browser to shut off power to the wireless networking card after loading a web page until I click on a web link, click on the home page button, select a bookmark, or enter a new URL in the address bar to take me to a different page. That way, you should be able to browse the web a lot longer than you would be able to do by having the wireless network card on during the whole web browsing session. Does the wireless card have to be constantly on to maintain the wireless connection?
